Ctrl+tab is horrendously slow in the new update

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: 1.131.0 (Commit e4c7e7b1d6d060162f4aa7f8225271b67ce1df75)
- OS Version: Windows 11 25H2 (Build 26200.8875)

Steps to Reproduce:

1. Press ctrl+tab in a project
2. Notice delay between keystroke and action completing

Below is a video with corresponding audio, listen (may need to increase volume) to the time between the keystroke and the action actually completing.

This was lightning fast before the new UI overhaul, however since then it has become a downright annoyance to working on things.

This is an incredibly small project so its not that, nor am I below minimum requirements (PC has a Ryzen 5900X, 64GB of RAM and an Nvidia RTX A2000 12GB). *Yes I know I had a lot open but most is idle in the background. CPU is at 4% and RAM not even halfway.*

Potential root cause - I think the new fade animation on the ctrl+tab menu is blocking and that is what is causing this delay.

# EDIT

Going back to classic UI and disabling the modern one alleviates the issue.
